(FRAME-INFO (STRING "Objectives. Learn the major tracts that convey motor commands from the brainstem to motor neurons and interneurons in the spinal cord. Four tracts that descend to the spinal cord and influence movement originate in the brainstem: the tectospinal, rubrospinal, reticulospinal, and vestibulospinal tracts. Be able to identify \(at least approximately\) their origin from specific nuclear groups and the main sources of input to these nuclear groups, the position of the tracts in the brainstem and cord, the extent of their bilaterality, and their general effects on motor neurons in the spinal cord."))
